NASHUA - Amid a whirlwind of accusations against her and her husband, Mayor Donnalee Lozeau today will hold her first press conference since taking office six years ago.

Since Lozeau issued a statement on Oct. 29 claiming the Nashua Police Department launched politically motivated investigations into her husband, David, and herself over the last several years, the mayor has remained relatively quiet this week about the matter.

Previously, she said the attempt by one or more persons in the police department to "start a smear campaign based on an unfounded investigation to achieve political goals is shocking and appalling."

She has maintained that an old police investigation involving her husband, former bail commissioner David Lozeau, resurfaced after she issued her State of the City address earlier this year and publicly called on the five police unions to negotiate new contract agreements with retroactive health care concessions.

The police investigation began in 2009 after a confidential informant - identified by David Lozeau as Tom Brennan, a man he sued in 2008 over a dispute about a truck - accused the Lozeaus of bid rigging and drug use, and made allegations of questionable practices by David Lozeau in his position as a bail commissioner. The mayor's husband resigned from that post earlier this year at the height of the allegations.

"Let me say this as clearly as I possibly can: I have not engaged in criminal activity of any kind. The suggestion that I committed any misconduct of any kind is unfounded, unsubstantiated and untrue," Mayor Lozeau said last week.

Her husband echoed those comments while releasing about 100 pages of police records that resulted in no criminal charges.

However, Police Chief John Seusing fired back this week contending the police investigation involving the Lozeaus, which included oversight by the New Hampshire Attorney General's Office, was never closed but simply suspended pending additional information.

Seusing said a recorded phone conversation revealed that "Commissioner (David) Lozeau exposed the identity of Nashua Police Department confidential informants, who assisted the Narcotics Intelligence Division with drug investigations."

He went on to say that the investigation was well under way prior to the mayor's negative remarks earlier this year about the police union bargaining agreements.

Seusing said the mayor's accusations that the department conducted a smear campaign are absolutely false.

Today's press conference has been scheduled for 11:30 a.m. at Nashua City Hall.
